It is detected that the upper surface of the 510 is not in contact.

When the upper sensor 550 detects that the upper surface of the upper panel 510 is not in contact, the upper sensor 550 transmits a signal that is not in contact with the microcomputer MICOM that controls the main body 100. The signal transmitted to the microcomputer MICOM transmits a signal to the damper 590, and the damper 590 transmits a signal in a state where the upper surface sensor 550 and the lower surface of the kimchi module 200 do not contact each other. Will be received.

When the damper 590 receives a signal in a state where the upper surface sensor 550 and the lower surface of the kimchi module 200 are not in contact with each other, the damper 590 operates to open / close means provided in the refrigerant pipe 600 ( 580,580 '). When the opening and closing means 580 and 580 'are operated, the refrigerant pipe 600 is closed. When the refrigerant pipe 600 is closed, the flow of the refrigerant which is a working fluid flowing into the refrigerant pipe 600 is regulated.

When the storing or withdrawal of the storage container 140 containing the kimchi and the food is completed, the user grips the door handle 122 and pulls the door 120 backward. When the door 120 is retracted backward, the opened upper surface of the storage space 160 is shielded. In this case, the lower surface of the storage space 160 is in contact with the upper sensor 550 mounted on the upper surface of the upper panel of the module connector 500.

When the bottom surface of the storage space 160 and the upper surface of the upper surface panel 510 of the module connector 500 is detected by the upper surface sensor 550, the upper surface sensor 550 is transferred from the upper surface sensor 550 to the MICOM. The contact signal is sent. The contact signal received by the MICOM is transmitted to the damper 590. The damper 590 controls the opening and closing means 580 and 580 'by the contact signal received by the damper 590 to open the refrigerant pipe 600. When the coolant pipe 600 is opened, the flow of the coolant, which is a working fluid flowing inside the coolant pipe 600, is smooth.

Meanwhile, even when the refrigerating module 300 is withdrawn and withdrawn, the upper sensor 550 and the lower sensor 560 mounted on the module connector 500 detect whether or not a contact is made. When the contact between the refrigeration module 300 is detected by the upper sensor 550 and the lower surface sensor 560, the inside of the refrigerant pipe 600 in the same manner as the method of detecting the contact of the kimchi module 200. It controls the flow of the refrigerant flowing to the.

In addition, when any one of the upper sensor 550 and the lower sensor 560 is detected not in contact, the damper 590 receives a signal that the contact does not contact to close the refrigerant pipe 600 do. When the refrigerant pipe 600 is closed, the flow of the refrigerant flowing inside the inner pipe 600 is regulated.

Therefore, when the kimchi module 200 and the refrigerating module 300 are drawn out to the front and the upper surface of the storage space 160 is opened, each sensor mounted on the module connector 500 detects contact. . When each of the kimchi module 200 and the refrigeration module 300 is detected in a non-contact state by each sensor, the refrigerant pipe 600 is closed to regulate the flow of the refrigerant.

When the kimchi module 200 and the refrigeration module 300 are introduced into the main body 100 and the upper surface of the storage space 160 is shielded, each sensor mounted on the module connector 500 is provided. It detects the contact. When the kimchi module 200 and the refrigeration module 300 is detected in contact by each sensor, the refrigerant pipe 600 is opened to smooth the flow of the refrigerant.

That is, when the kimchi module 200 and the refrigerating module 300 is withdrawn forward, the refrigerant does not flow, and when the kimchi module 200 and the refrigeration module 300 is drawn into the main body 100, The refrigerant flows.

The scope of the present invention is not limited to the above-exemplified embodiments, and many modifications may be made based on the present invention to those skilled in the art within the above technical scope.

For example, in the above-described embodiment, each sensor is configured to be mounted at each corner portion of the module connector 500, but it may be possible to be mounted at different positions in different quantities.
